JOHN WILLIAM SHEPPARD, OF BISBEE, ARIZONA TERRITQRY.

WRENCH.

To all whom it may concern:

Be it known that I, JOHN VILLIAM SHEP- YARD, citizen of the United States, residing at Bisbee, in the county of Cochise, Arizona Territory, have invented certain new and useful Improvements in renches, of which the following is a specification.

The object of this invention is an improved apparatus for tightening the tire bolts of a vehicle wheel and is designed particularly for use in connection with a drill press.

WVith this and other objects in view as will more fully appear as the description proceeds, the invention consists in certain constructions and arrangements of parts that I shall hereinafter fully describe and then point out the novel features in the appended claim.

For a full understanding of the invention and the merits thereof and to acquire a knowledge of the details of construction reference is to be had to the following description and accompanying drawings, in which Figure 1 is a side elevation of my improved apparatus with parts in section, and Fig. 2 is a top plan view thereof.

Corresponding and like parts are referred to in the folowing description and indicated in all the views of the drawings by the same reference characters.

Referring to the drawings the numeral 1 designates a frame preferably constructed of metal and comprising a base member 2 and an arm 3 formed at one end of the base member 2 and extending vertically therefrom and then horizontally, the horizontal portion being parallel to and spaced from the base member as shown. In the rear end of the base member 2 is adj ustably secured a forked brace 4: which is designed to extend partially around the standard of a drill press to hold the apparatus in proper position.

J ournaled in a vertical position in the base member 2 and the horizontal portion of the arm 3 is a shaft 6 which extends upwardly through the arm 3. The upward extension of shaft is reduced as shown at 7 and is designed to fit into the socket of a drill press, the shaft being thus adapted to be revolved by the press. A gear wheel 8 is mounted on the shaft between the base plate 2 and the arm 3 and is adapted to revolve with said shaft. This gear wheel 8 meshes with a relatively small spur pinion 9 removably mounted on a socket wrench 10 which is jour- Specification of Letters Patent.

naled in a vertical position in the base member 2 as shown.

A lever 11 is fulcrumed at one end on the outer extremity of the arm 3, so that it is free to move in a vertical plane, said lever extending outwardly from the end 3 in longitudinal alinement therewith and being formed between its ends with a lug 12 designed to register with the socket of the wrench 10.

The front end of the base member 2 of the supporting frame is formed with a transverse opening 2 and a vertically extending socket communicating therewith. A bolt cutter 13 is rotatably mounted in the opening 2 and is provided with a crank-handle ll, so that it may be turned to clip off the projecting end of the bolt after the nut has been screwed thereon.

To attach my improved apparatus to a drill press the brace t is adjusted in the frame 1 so that when the standard of the drill press is received in the fork of said brace the reduced portion 7 of the shaft will be in alinement with the socket of the press. The reduced portion 7 is then secured in the said socket and the apparatus is ready for work.

In the practical operation of the invention, part of the rim of a vehicle wheel is held over the wrench 10 so that the nut of a tire bolt is received in the socket of said Wrench. The lever 11 is held so that the tooth-like lug 12 thereof will bear against the head of the bolt to prevent the bolt from turning. Power is applied from the drill press and the wrench is operated by means of the shaft and gear wheels so that it will effectually tighten the nut on its bolt. It will be readily understood that the apparatus may be also employed to loosen the tire bolt nut-s if such should be desired. After the tire bolt has been tightened by the wrench, the protruding end of such bolt is inserted in the crank bolt cutter and is clipped off thereby.

Having thus described the invention, what I claim is:

An apparatus of the character described, comprising a frame consisting of a base member and an integral arm formed at one end of the base member and extending upwardly therefrom and thence over and spaced from the base member with its extremity terminating short of the adjacent extremity of the base member, the base member and arm being parallel with each other, a socket wrench ournaled in the base member beyond the arm, a pinion mounted on said wrench, a gear wheel meshing with said pinion, a shaft on which said gear wheel is mounted, said shaft being journaled in the arm and base member and the pinion being held between the arm and base member, the arm being forked at its extremity, and a bolt-holding lever fulorumed at one end on the forked extremity of said arm to swing in a Vertical plane and extending out from the base ,member in longitudinal alinement therewith, the lever being formed interme- 15 diate of its ends with a depending lug, as and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
